The Siemens electric three-way temperature control valve is a widely used solution in the field of temperature regulation. It operates by controlling the flow of the primary heating or cooling medium into heat exchangers, air conditioning units, or other thermal equipment to maintain the desired outlet temperature. When system load changes, the valve adjusts its opening to compensate for fluctuations, ensuring stable and accurate temperature control.
This device is an advanced application of electric control valves, specifically designed for precise temperature management. It consists of a German Siemens controller, actuator, sensor, and flow control valve. The actuator features mechanical-electro-hydraulic operation, adjustable settings, strong shut-off force, and customizable flow characteristics (linear or equal percentage), along with power-off protection for safety. The valve body is designed for high precision, with excellent linearity, a large adjustment range, tight sealing, high-temperature resistance, and anti-cavitation properties. Its flexible controller functions allow for control of fluid flow, pressure, differential pressure, temperature, enthalpy, and air quality. Additionally, it is commonly used for automatic differential pressure bypass control in return systems.
The Siemens electric three-way temperature control valve is applied in various areas, including:
1. Heat exchangers or heat exchange units in heating systems
2. Domestic hot water systems
3. Air conditioning water or air systems
4. Temperature control in industrial production processes
Key advantages of this product include:
1. Adjustable control parameters that can be optimized based on on-site conditions
2. Advanced calculation capabilities to predict temperature trends and ensure accurate control
3. Real-time temperature monitoring and valve status observation via the controller
4. Scalable features such as temperature compensation, remote configuration, day/night and summer/winter mode switching, priority settings, cascade control, over-temperature alarms, remote communication, and central monitoring
5. Optional circuit breaker protection to automatically close the valve during power outages
6. Multiple intelligent energy-saving modes for unattended operation and cost efficiency
When selecting a Siemens temperature control valve, consider the following:
1. Choose the valve material, flow capacity, and actuator shut-off force based on the type of medium (steam or hot water), temperature, pressure, and system conditions
2. For steam control, ensure the steam is at least 98% dry. Superheated steam may require recalculating due to changes in the adiabatic index and viscosity
3. The relationship between flow rate and pressure difference is square root-based. Excessive pressure differences can cause noise and cavitation, reducing valve life and potentially leading to serious accidents
4. An ideal temperature regulation curve ensures effective control. Unless required for fast heating systems, the valve should have equal percentage or parabolic characteristics
5. Avoid using the electric temperature control valve as a long-term shut-off valve; close it when the system is off
6. Do not convert a two-way valve into a three-way valve by removing the blind flange
7. Ensure compatibility with third-party equipment and follow all safety standards
8. This valve is not suitable for direct water supply systems. A circulation system must be added. If used with a hot water heat exchanger, a thermal storage tank is also necessary
